Imagine you have a lot of information that you want to give to someone else. However, instead of giving it to them yourself, you give it to a special helper called a marshal. The marshal takes all the information and organizes it in a special way so that the person you want to give it to can easily understand it.
In computer programming, marshal is like that special helper. It is a tool that helps programmers take information or data and organize it in a way that is easier to store or send to other places. Imagine you have a program that needs to send data to another program. Without the marshal, the data might be disorganized and difficult for the program to understand. However, with the marshal, the data can be organized into a specific format that both programs can understand easily.
So, the marshal is a tool that makes dealing with data a lot simpler and easier for programmers, just like your special helper who helps you share information in a way that is easy for others to understand.
